White dwarf stars are hot , but not very bright, because they are so small.
An example is "Sirius B", the companion of "Sirius A", the brightest star in the sky.
A star is a ball of gas that is very hot and very bright.
For example, galaxies are very large, very massive, very bright, and (most of them) very far away from us.
Venus is sometimes called "the evening star", although it is a planet. This because it is very bright and always appears close to the Sun in the sky. So, sometimes it appears in the evening as the Sun sets, looking like a very bright star.
Polaris, the North Star or pole star, is a very bright super giant that is orbited by four companion stars. While the system is 434 light years (2.549e+15 miles) from Earth, the combination of the very large, bright primary star with the orbiting companions makes Polaris seem very bright in the northern sky, and brightness appears large in the night sky.
Venus is called the morning star.
How bright a star appears depends on both its actual brightness and how far away it is. The farther away a star is, the dimmer it appears. A bright but very distant star many therefore appear dimmer than a less bright star that is closer to us.
Canopus is a very bright star. It is in the southern constellation of Carina.
A star is a ball of gas that is very hot and very bright.
VERY hot and bright.
The brightness of a star depends on its temperature, size and distance from the earth. The measure of a star's brightness is called its magnitude. Bright stars are first magnitude stars. Second magnitude stars are dimmer. The larger the magnitude number, the dimmer is the star.The magnitude of stars may be apparent or absolute.
They are very brittle and they can get up to a very bright temperature
a star
This could be a white dwarf. Its essentially a `dead star` as nuclear reactions no longer take place, but it remains very hot for millions of years from residue heat. They are very small though, compared with other stars or the size they used to be. If a hot bright star is very very far from earth then this also will appear dim from earth. It may have a low apparent magnitude (but a high absolute magnitude).
They are very brittle and they can get up to a very bright temperature
No bright means that something is too light. for example: the sun is very "bright."
The 3 factors that affect a star's brightness as viewed from earth, are: The star's age, distance from earth, and actual magnitude (scale a star's brightness is measured in).
OUr very own sun is an example of a middle aged star
